Description

Technical Field

[0001] This invention relates to the field of filter housing technology, specifically a movable filter housing for PVC massage pools. Background Technology

[0002] The PVC massage pool filter box is an independent water circulation and purification device adapted to household inflatable PVC massage pools. The whole is a movable integrated box structure, integrating water circulation, impurity filtration, auxiliary sterilization and movable adjustment components. It has a compact structure, is easy to disassemble and assemble, and can be quickly connected to the pool pipeline. It is specially designed for small soft pools. Due to the limited water volume of massage pools, the water is used in a closed circulation for a long time. Human skin flakes, sweat, hair, dust and organic matter are easy to continuously mix into the water. In addition, the closed and humid environment is prone to the growth of algae and bacteria, resulting in turbid water and odor. This not only affects the user experience, but also irritates the skin and poses hygiene risks. At the same time, frequent pool water changes are costly and wasteful of water. Manual cleaning is time-consuming and laborious.

[0003] However, existing filter housings are difficult to switch quickly between stationary and mobile states during use, making equipment handling and relocation extremely inconvenient, limiting space placement, resulting in a poor overall user experience, and making it difficult to guarantee structural stability and service life. Summary of the Invention

[0004] The purpose of this invention is to provide a movable filter box for PVC massage pools. By setting up a retractable section, it solves the problems of existing filter boxes, such as difficulty in quickly switching between stationary and mobile states during use, inconvenience in equipment handling and position adjustment, large limitations in site placement, poor overall operating experience, and difficulty in guaranteeing structural stability and service life.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a movable filter housing for a PVC massage pool, comprising a filter housing and further comprising: a retractable section mounted on the filter housing; a locking section disposed on the retractable section; a folding section mounted on the filter housing; the retractable section includes a lifting assembly disposed on the filter housing; and two sliding assemblies, both mounted on the filter housing; the lifting assembly includes a fixed block fixedly connected to the bottom of the filter housing, the fixed block having two sliding grooves, each groove containing a slider, the bottom of each slider being fixedly connected to a support plate, both support plates having bidirectional threaded rods threadedly connected to the two support plates, both support plates having sliding rods threadedly connected to the two support plates, and both support plates having movable parts with opposite threads on the two bidirectional threaded rods; each movable part includes two casters fixedly connected to the bottom of the support plate, the casters being mirror-shaped.

[0006] Furthermore, the locking part includes a friction assembly disposed on the retracting part; and a pressing assembly mounted on the filter housing.

[0007] Furthermore, the folding portion includes an extension assembly disposed on the filter housing; and a storage assembly mounted on the filter housing.

[0008] Furthermore, the sliding assembly includes a support plate two fixedly connected to the bottom of the filter box. The support plate two has two sliding grooves two, and the inner walls of the two sliding grooves two are slidably connected to sliders. The two sliders are rotatably connected to the bidirectional threaded rod and the sliding rod one, respectively.

[0009] Furthermore, the friction assembly includes a friction groove formed on the second support plate, a friction block is provided in the friction groove, and a handle is fixedly connected to the right side of the bidirectional threaded rod, with the friction block and the friction groove being adapted to each other.

[0010] Furthermore, the extrusion assembly includes a friction ring fixedly connected to the right side of the friction block, and a spring is provided between the friction block and the handle. The right side of the spring is fixedly connected to the handle, and the left side of the spring is fixedly connected to the friction block. The initial state of the spring is a compressed state.

[0011] Furthermore, the extension assembly includes a placement slot formed on the support plate two and the filter housing. A connecting rod is fixedly connected to the inner wall of the placement slot, and a hinge rod is rotatably connected to the outer wall of the connecting rod. A slide rod two is slidably connected to the inner wall of the hinge rod, and a spring two is provided inside the hinge rod. The top of the spring two is fixedly connected to the slide rod two, and the bottom of the spring two is fixedly connected to the bottom inner wall of the hinge rod. The slide rod two is confined inside the hinge rod and will not slide out. The spring two is in a compressed state when stored.

[0012] Furthermore, the storage component includes an adapter slot opened above the placement slot, a handle two is fixedly connected to the top of the slide rod two, and an auxiliary ring is rotatably connected to the outer wall of the slide rod two. The auxiliary ring has a certain friction when it rotates on the slide rod two, so it will not rotate randomly.

[0013] The present invention has the following beneficial effects: 1. This invention features a retractable section. By rotating a handle, a bidirectional threaded rod is driven to rotate synchronously, causing two sets of support plates to close in opposite directions. An inclined sliding groove and a sloping fixing block form an oblique guiding engagement, allowing the slider to slide along the inclined groove for limitation. Simultaneously, a sliding rod provides lateral guidance and limitation, and a sliding ring adaptively slides within the second sliding groove to compensate for vertical displacement, achieving smooth and coordinated lifting of the entire structure. The omnidirectional wheels can be controlled to extend smoothly and contact the ground, quickly completing the landing and relocation of the filter box. The structure has good adaptability, is simple and labor-saving to operate, and effectively improves the convenience and flexibility of equipment handling and relocation.

[0014] 2. This invention, by setting a locking part, pulls the friction ring laterally, causing the friction block to move synchronously and compress the spring, making the friction block slide axially along the bidirectional threaded rod. This overcomes the friction limiting effect, forcibly separating the friction block from the friction groove, releasing the locking constraint between the two, thereby canceling the locking part's locking and fixing of the retractable part, completing the unlocking operation, and providing structural activity conditions for the retractable part's extension and contraction adjustment. The limiting locking is achieved by friction locking, which has strong locking stability and can effectively prevent the retractable part from being moved or extending and contracting by external force, ensuring the structural stability of the filter box when it is placed statically.

[0015] 3. This invention features a folding section. By pressing the auxiliary ring, the slide bar 2 moves downward and compresses the spring 2, causing the handle 2 to disengage from the limiting structure of the adapter groove. Then, by pulling the auxiliary ring laterally, the locking restriction is completely released. Utilizing the elastic restoring effect of the spring 2, the slide bar 2 and handle 2 automatically extend outward. With the unfolded handle 2, the filter box can be dragged to complete the equipment relocation operation. The traction handle can be quickly unfolded, significantly reducing the difficulty of dragging and moving the filter box. The folding and storage design effectively reduces the overall space occupied, and the storage is neat and not easily damaged by bumps.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8 As shown, the present invention is a movable filter box for a PVC massage pool, including a filter box 111, and further including: a retractable part 2, which is installed on the filter box 111; a locking part 3, which is disposed on the retractable part 2; and a folding part 4, which is installed on the filter box 111. The retraction section 2 includes a lifting assembly 21, which is mounted on the filter housing 111; and two sliding assemblies 22, both mounted on the filter housing 111. The lifting assembly 21 includes a fixing block 211 fixedly connected to the bottom of the filter housing 111. The fixing block 211 has two sliding grooves 212, each containing a slider 213. The bottoms of the two sliders 213 are fixedly connected to support plates 214. Two bidirectional threaded rods 215 pass through the support plates 214 and are threadedly connected to them. Sliding rods 216 pass through the support plates 214 and are slidably connected to them. Each of the support plates 214 is equipped with a movable component. The two threads on the bidirectional threaded rod 215 are opposite. The movable component includes two casters 217 fixedly connected to the bottom of the support plate 214. The two casters 217 are arranged in a mirror image. The sliding component 22 includes a support plate 221 fixedly connected to the bottom of the filter box 111. The support plate 221 has two grooves 222. The inner walls of the two grooves 222 are slidably connected to sliders 213. The two sliders 213 are rotatably connected to the bidirectional threaded rod 215 and the slide rod 216, respectively. By setting the extension part 2, the casters 217 can be extended and put into contact with the ground, and the filter box 111 can be quickly moved to the ground. The structure has good adaptability, simple operation and labor saving, and effectively improves the convenience and flexibility of equipment transportation and relocation.

[0022] The locking part 3 includes a friction assembly 31, which is disposed on the retractable part 2; and a pressing assembly 32, which is installed on the filter housing 111. The friction assembly 31 includes a friction groove 311 formed on the support plate 221, and a friction block 312 is disposed in the friction groove 311. A handle 313 is fixedly connected to the right side of the bidirectional threaded rod 215. The friction block 312 is adapted to the friction groove 311. The pressing assembly 32 includes a friction ring 321 fixedly connected to the right side of the friction block 312. A spring 322 is disposed between the friction block 312 and the handle 313. The right side of the spring 322 is fixedly connected to the handle 313, and the left side of the spring 322 is fixedly connected to the friction block 312. The initial state of the spring 322 is a compressed state. By setting the locking part 3, the retractable part can be effectively prevented from being moved by external force and from extending or retracting on its own, thus ensuring the structural stability of the filter housing 111 when it is placed still.

[0023] The folding part 4 includes an extension assembly 41, which is disposed on the filter housing 111; and a storage assembly 42, which is also mounted on the filter housing 111. The extension assembly 41 includes a placement groove 411 formed in the support plate 221 and the filter housing 111. A connecting rod 412 is fixedly connected to the inner wall of the placement groove 411. A hinge rod 413 is rotatably connected to the outer wall of the connecting rod 412. A slide rod 414 is slidably connected to the inner wall of the hinge rod 413. A spring 415 is disposed inside the hinge rod 413. The top of the spring 415 is fixedly connected to the slide rod 414, and the bottom of the spring 415 is fixedly connected to the bottom inner wall of the hinge rod 413. The second slide bar 414 is confined within the hinge bar 413 and will not slide out. The second spring 415 is in a compressed state when stored. The storage component 42 includes an adapter slot 421 opened above the placement slot 411. The top of the second slide bar 414 is fixedly connected to the second handle 422. The outer wall of the second slide bar 414 is rotatably connected to the auxiliary ring 423. When the auxiliary ring 423 rotates on the second slide bar 414, it has a certain friction force, so it will not rotate randomly. By setting the folding part 4, the traction handle 422 can be quickly unfolded, which greatly reduces the difficulty of dragging and moving the chassis. The folding storage design can effectively reduce the overall space occupied, and the storage is neat and not easily damaged by bumps.

[0024] When in use, the retractable part 2 needs to be extended downwards when the filter box 111 needs to be moved. However, before extending, the locking part 3 needs to be opened. When opened, the friction ring 321 is pulled to the right. At this time, the friction block 312 will move accordingly. As it moves, the friction block 312 will squeeze the spring 322. The friction block 312 will slide on the bidirectional threaded rod 215. With continuous movement, the friction block 312 will disengage from the friction groove 311. At this time, the restriction on the retractable part 2 can be released. The locking part 3 is used to lock the retractable part 2. After unlocking, turn handle 313. Handle 313 will rotate along with the bidirectional threaded rod 215. When the bidirectional threaded rod 215 rotates, it will bring the two support plates 214 closer together. When the support plates 214 are close together, they will move the slider 213. When the slider 213 moves, it will slide in the slide groove 212. Because the fixed block 211 is inclined, the slide groove 212 is also inclined. As the support plates 214 and the slider 213 move, they will move downward. During the movement, the support plates 214 will slide on the slide rod 216. The sliding ring 223 on the support plates 214 and the bidirectional threaded rod 215 will also slide in the slide groove 222 to match the up and down movement of the support plates 214. As the movement progresses, the caster wheel 217 will contact the ground. After the caster wheel 217 is in full contact with the ground, the filter box 111 can be pushed. At this time, the folding part 4 can be unfolded, making it easier to push the filter box 111. When it needs to be unfolded, press the auxiliary ring 423. At this time, the auxiliary ring 423 will move the slide bar 414 downward. When the slide bar 414 moves downward, it will squeeze the spring 415. As it moves, the handle 422 will disengage from the adapter slot 421. At this time, pull the auxiliary ring 423 to the right. The handle 422 will disengage from the adapter slot 421. After disengagement, the spring 415 will push the slide bar 414 to extend outward. This allows the handle 422 and the slide bar 414 to be extended. At this time, the handle 422 can be pulled to drag the filter box 111, thereby achieving the effect of moving the filter box 111.
